I recently got my IFR rating in my RV-6. I'm flying with a Dynon Skyview system and a Garmin 430W. I finished up my training in Kansas, at GATTS. My question is this: When I was in Kansas we flew into 4 different airports and always asked the tower for an approach. For example into KIXD I would call the tower tell him I was west of the airport at 2500 and ask for the RNAV36. He would say report UNOXY and in I went. Same for the other airports in the area. At home in NY on Long Island, the towers say they cannot give me an approach. I have to call Approach and they give me a frequency. No problem, I do it, but what is the difference between the areas? Is it because we are busier here in the north east? Where can I call towers directly, and how would I know this? How is it where you are?
